数词
数词分基数词和序数词。基数词表示数目，序数词表示顺序。
一、基数词的构成
1．1—12的基数词是独立的单词，即：
2．13—19的基数词以-teen结尾。如：但13，15，18较特殊，13—15—18—。3．20—90的整十位均以-ty结尾。如：sixty，seventy，但20，30，40，50，80，90较特殊，20—30—40—50—80—90—。
4．十位数与个位数之间要加连字符号“-”，如：28—twenty-eight，96—ninety-six。
5．百位和十位（若无十位则和个位）之间加and，如：148—one hundred and forty-eight 406—four hundred and six。
6．hundred（百），（千），（百万），（十亿）等前面即使有具体的数词，也不能在它们的后面加s。如：600—six hundred，8百万—-
7．2，510＝two thousand five hundred and ten；84，296＝eight-four thousand two hundred and ninety-six；8．hundred，thousand，million用复数形式修饰名词时要用“of＋复数名词”，如：数以百计的年轻人hundreds of young people；数以千计的书thousands of books。注意：hundreds of ／thousands of／millions of ＋复数名词，其前面不能加具体的数词，但可加several或many。遵循两无原则
9．基数词＋单数名词＋形容词构成合成形容词。如：一个五岁的男孩a five-year-old boy；一座800米长的桥；
10．句型：主语＋is ＋about（大约）／over ＝more than（超过）／nearly（接近）＋具体数词＋meter（s）／kilometer（s）／kilo（s）long ／high ／tall ／deep ／away等。如：长江长6300公里。The Changjiang River is 6，300 kilometres long．
二、序数词
1．基数词变序数词可利用口诀巧记：“一、二、三，特殊记，八去“t”，九去“e”，“ve”要用“f”替，见“y”变成“i”和“e”，词尾加上“th”，若是遇到几十几，只变个位就可以。”第一、第二、第三分别：，，，eight—eighth nine—，five—，twelve—，twenty—，forty—fortieth，twenty-five —。
2．其余情况均在基数词后加th。如：six—sixth, nineteen—nineteenth , hundred—hundredth, thousand —thousandth等。
3、（3）序数词的缩写形式为：阿拉伯数字加上这个词的末尾两个字母。
1st 2nd，3rd，4th，20th，21st，22nd，23rd
三、数词的用法
1. 基数词的用法
(1) 基数词在句中主要用作主语、宾语、定语、表语、同位语，例如：
(2) 表示一个具体数字时，hundred, thousand, million一律不用复数；在表示一个不确定数字时则用复数。例如：Our country has a population of 1,300 million people. There are three thousand students in our school. After the war, thousands of people became homeless.
(3) 表示“……十”的数词的复数形式可用来表示人的岁数或年代，例如：
He is in his early thirties． He died still in his forties． This took place in 1930s．(4) 表示时刻用基数词。例如：
We get up at six.
表示“几点过几分”，用介词past,但须在半小时以内。例如：
ten past ten, a quarter past nine, half past twelve
表示“几点差几分”用介词to, 但分数须在半小时以上。例如：
twenty to nine, five to eight, a quarter to ten
表示“几点几分”还可直接用基数词。例如：
seven fifteen, eleven thirty, nine twenty
2. 序数词的用法
（1）（1）序数词作定语时，一般要与定冠词或物主代词连用。
eg. Tom is their second son. He is the first one to come here. John lives on the fifteenth floor．
（2）序数词有时前面可加不定冠词来表示“再一”，“又一”这样的意思，例如：
We'll have to do it a second time．Shall I ask him a third time？
（3）表示日期。
①年份，每两位数读一个词。②先月后日，日子要读成序数词。③先日后月，加OF。年，月。日的话年放最后，用逗号隔开。
（4）表示分数时，分子用基数词表示，分母用序数词表示。分子大于1时，分母加-s。例如：
three fourths, one second, two fifths
（四、数词在生活中的应用
1．钟点的表示：小时、点钟、分钟、秒钟要用基数词。
2．编号的表示：
①Lesson One ＝the first lesson第一课；Bus No．3＝the No．3bus 3路公共汽车；
②表示住所时不用“No．”如：302房间—Room 302（读作：room three o two）；
③如果编号的数词比较长，一般用基数词。如：Page 457第457页；
⑤电话号码，用基数词，可单个读，重复的数字也可读“double”，如：3855633—three eight five five（double five）six three three（double three）。
3．年月日的表示：。4．分数的表达：
5．倍数的表达：一倍用once，两倍用，两倍以上用基数词＋。如：5倍。
6、小数的小数点读作point，零读作o［ｕ］或zero,小数点后面的数字按个位基数词依次读出。
7、百分数(%)，读作per cent (percent),但不论是多少均用作单数形式不能加s。
8、表示日期有两种说法和四种写法，如：2月1号英语表达法为：the first of February而美语为February (the) first,但其书写上可有四种写法①February 1 ②February 1st ④1/2。
五、特殊用法
1．数词作主语，谓语动词用单数。如：Two months is quite a long time．Four and two is six．What's two and three？
2．一个半小时（一年半，一个半月可类推）one／an hour and a half ＝。
3．不定冠词用在序数词前表又一、再一。如：I've tried three times，let me try a fourth time．意为：我已经试过三次，让我再试一次吧。
4、基数词一般是单数形式，但下列情况，常用复数：
a. 与of 短语连用，表示概数，不能与具体数目连用，如scores of people 指许多人；
b. 在一些表示"一排"或"一组"的词组里；
如：They arrived in twos and threes. 他们三三两两的到达了。
c. 表示"几十岁"；
d. 表示"年代"，用in +the +数词复数；
e. 在乘法运算的一种表示法里，如：3 x 5 = 15 Three fives is (are) fifteen.
5、半小时为half an hour, 半天为half a day, 半镑为half a pound, 尽量避免用half a year, half a month, 要用six months, two weeks 或fifteen days 要注意的是Half of the work is done Half of the books are sold. 当Half 作名词时，其谓语动词要看of后面的名词而定。如名词是不可数名词则用单数谓语动词，如是复数名词时，则要用复数谓语动词。要注意的是一个半的表达法，如：One and a half apples is left on the table.其名词要用复数，但谓语动词则要用单数。
6、在句首的数字要用文字而不要用阿拉伯数字，如数字过大则应放于句中，用阿拉伯数字。如：
There are 166 students playing on the ground.
［误］60 students are playing on the ground.
［正］Sixty students are playing on the ground. ［答案］A.

数词 I.定义与分类 数词是指表示数目多少或顺序先后的词。表示数目多少的数词叫基数词，如one, five, ten, thirty, sixty-five 等；表示顺序先后的数词叫序数词，如first, sixth, tenth, twenty-first 等。数词用法相当于名词和形容词，在句中可用作主语、宾语、表语、定语、同位语等。 II. 基数词 1. 英语中没有“万”这个读数单位，要表示汉语中的“万”，英语需借用thousand一词，如“一万”用“十个千”表示(ten thousand)，“十万”用“一百个千”表示(one hundred thousand)。 2. 用作基数词单位的hundred, thousand, million, billion 通常不带复数词尾-s，但若用于表示数百、数千、数百万这样的泛指，则用复数。如： About two thousand people died in the earthquake. 大约有两千人在地震中丧生。 Thousands of people go to the seaside every year. 每年成千上万的人到海滨去。 3. 表示整十的基数词用复数形式可以表示人的大约岁数或年代。如： He is in his early twenties. 他才二十出头(from 。 This took place in the 1930s. 这事发生在20世纪30年代。 III. 序数词 1. 许多序数词是由相应的基数词后加词尾-th构成的，如four / fourth，six / sixth，ten / tenth，sixteen / sixteenth，但是nine变为序数词是ninth，而不是nineth。 2. twentieth, thirtieth, fortieth 等表示整十的序数词，由相应的基数词将词尾y改为ie，再加-th 构成。 3. first, second, third 通常可缩写为1st, 2nd, 3rd。凡是以th结尾的序数词可缩写为“基数词+th”：4th, 5th, 9th, 11th, 60th, 128th等。 4. 非整十的多位数，将个位数变成序数词即可：twenty-first(第21)，thirty-sixth(第36)， ninety-ninth(第99)，three hundred and sixty-fifth(第365)等。 5. hundred, thousand, million 等序数词形式为hundredth, thousandth, millionth 等。 6. 序数词前通常要用定冠词，但表示考试或比赛等的名次时，通常可省略其前的定冠词。如：My room is on the second floor and his on the third. 我的房间在三楼，他的房间在四楼。 He was (the) third in the exam. 他考试得了第三名。 注：有时序数词前不用定冠词，而用不定冠词，表示次第在原有基础上的增加。如： We'll have to do it a second time. 我们得再做一次(from 。 序数词前用定冠词和不定冠词的区别在于：定冠词表特指，不定冠词表泛指，有类似another的意思，但比another 的意思更明确。 IV. 分数、倍数、小数和百分数 1. 分数。 (1)分数由基数词和序数词构成：分子用基数词，分母用序数词，当分子超过“1”时，分母用复数。如： two thirds=2/3 three fifths=3/5 注：1/2 通常读作 a [one] half，一般不读作a second；1/4 可读作 a [one] fourth，也可读作 a

▲掌握小数，分数、百分数和时间、日期的表达法。 【复习要点】 （一）基数词num. 基数词用来表示数目，或者说表示数量的词叫基数词。最基本的基数词如下表所示。 1 one 11 eleven 100 a hundred 2 two 12 twelve 20 twenty 1000 a thousand 3 three 13 thirteen 30 thirty 1，000，000 a million 4 four 14 fourteen 40 forty 10，000，000 ten million 5 five 15 fifteen 50 fifty 100，000，000 a hundred million 6 six 16 sixteen 60 sixty 1，000，000，000 a billion 7 seven 17 seventeen 70 seventy 8 eight 18 eighteen 80 eighty 9 nine 19 nineteen 90 ninety 10 ten 说明： 1．13—19是由个位数加后缀-teen构成。注意其中13、15的拼写是thirteen 和fifteen。 2．20—90由个位数加后缀-ty构成，注意其中20—50的拼写分别是twenty, thirty, forty 和fifty;80的拼写是eighty。 3．其它非整十的两位数21—99是由整十位数加连字符“-”，再加个位数构成。如：81 eighty-one。 4．101—999的基数词先写百位数，后加and再写十位数和个位数。如：691 six hundred and ninety-one。5．1000以上的基数词先写千位数，后写百位数，再加and，最后写十位数和个位数。 如：5893 five thousand eight hundred and ninety-three。在基数词中只有表示“百”、“千”的单位词，没有单独表示“万”、“亿”的单位词，而是用thousand（千）和million（百万）来表达，其换算关系为：1万=10 thousand;1亿=100 million; 10亿=a thousand million=a billion。 Hundreds of Thousands of 6．多位数的读法： 1）1000以上的多位数，要使用计数间隔或逗号“，”。即从个位起，每隔三位加一个间隔或逗号。第一个间隔或逗号前是thousand（千），第二个间隔或逗号前是million（百万），第三个间隔或逗号前是a thousand million或a billion(十亿)。 2）每隔三位分段以后就都成了101—999。读的时候十位数（或个位数）的前面一般要加and。如： 888，000，000读作：eight hundred and eighty-eight million。 基数词的用法： 1. 基数词在句中的作用 基数词的作用相当于名词和形容词，在句中可作定语、主语、宾语（介宾）、表语、同位语等。 例如：Three and five is eight. 3+5=8 （作表语）How many oranges do you want?你要多少桔子？ I want eight. 我要八个。（作宾语）There are eight boats in the lake. 湖里有八条小船。（作定语） 2．Hundred, thousand, million, dozen, score这些词前面如有表示具体数字的词，它们不能加“s”,反之则须加“s”, 并要与of短语连用。例如：
文言文中"之"的用法 一、之1.用作代词，又分几种情况：（一）可以代人、代物、代事。 代人多是第三人称。译为"他"（他们）、"它"（它们）。作宾语 或兼语，不作主语。例如：作《师说》以贻之。（《师说》，代 人，作宾语。）輮使之然也。（《劝学》，代物，作兼语。）人非 生而知之者。（《师说》，代事理，作宾语。）（二）指示代词，表 近指。可译为"这"，通常作复指性定语。如：均之二策。（《廉 颇蔺相如列传》）2.用作助词，也分几种情况：（一）结构助词，定语的标志。用在定语和中心语（名词）之间，可译为"的"， 有的可不译。如：若能以吴、越之众与中国抗衡。（《赤壁之战》）道之所存，师之所存也（《师说》）（二）结构助词，补语的标 志。用在中心语（动词、形容词）和补语之间，可译为"得"。 如：古人之观于天地、山川、草木、鸟兽，往往有得，以其求 思之深而无不在也。（《游褒禅山记》）（三）结构助词，宾语前 置的标志。用在被提前的宾语之后，动词谓语或介词之前，译 时应省去。如：宋何罪之有？（《公输》，即"宋有何罪"）（四）结构助词。当主谓短语在句中作为主语、宾语或一个分句时，" 之"用在主语和谓语之间，起取消句子独立性的作用，可不译。 译时也可省去。如：师道之不传也久矣！欲人之无惑也难矣！ （《师说》）悍吏之来吾乡，叫嚣乎东西。（《捕蛇者说》）孤之 有孔明，犹鱼之有水也。（《隆中对》）（五）音节助词。用在形 容词、副词或某些动词的末尾，或用在三个字之间，使之凑成
四个字，只起调整音节的作用，无义，译时应省去。如：顷之，烟炎张天。（《赤壁之战》）毛先生以三寸之舌，强于百万之师。 （《毛遂自荐》） [之"在文言文中常当代词.助词.动词用.其作用各不相同. 一. 作代词 1. 代人.如<项脊轩志>中的[先妣抚之甚厚".[之"可译作[她".代老妪. 2. 代物.如<烛之武退秦师>中的[若不阙秦.将焉取之".[之"代[土地". 3. 代事.如<邹忌讽齐王纳谏>中的[与坐谈.问之客曰".[之"代[与徐公孰美这件事". 4. 指示代词.如<寡人之于国也>中的[无如寡人之用心者".[之"可译作[这.这样"指上文[河内凶--亦然".[不若长安君之甚"<触龙说赵太后>.[之"译作[那样". 二. 作助词 1. 定语的标志.如<谏太宗十思疏>中的[代百司之职役哉".这里的[之"连结名词性定语[百司"和中心语[职役".可译作[的".表示限制的偏正关系.此句可译为[代管百 官的职事呢?".<过秦论>中的[东割膏腴之地.北收要害之郡"两个[之"分别连结形 容词性定语[膏腴".[要害"和中心词[地".[郡".表示修饰的偏正关系. 2. 补语的标志.如<捕蛇者说>中的[未若复吾赋不幸之甚也".[之"在这里作补语的标志.可译作[得".表示连结中心词[不幸"和补语[甚". 3. 宾语前置的标志(不译).如<烛之武退秦师>中的[夫晋.何厌之有".这里[何厌"是[有"的宾语.提前了.此句可译为[晋国(的欲望).有什么满足的(可能)呢?" 4. 定语后置的标志(不译).如<劝学>中的[蚓无爪牙之利.筋骨之强".两个[之"都作定语后置的标志.[之"字前是中心语.[之"字后是定语.此句可译为[蚯蚓(虽然)没有 锐利的爪牙.强健的筋骨". 5. 用在主谓之间.取消句子独立性(不译).如<归去来兮辞>中的[善万物之得时.感吾生之行休".这里两个[之"用在主谓词组之间.表示这一词组不能单独成句.此句 可译为[(我)羡慕一切生物得到复苏的时节其时.感叹自己的年华行将结束." 6. 用在主语和介词结构之间.表示它们已经成为一个整体.强调.突出这个介词结构的意义.(不译).如<寡人之于国也>中的[寡人之于国也.尽心焉耳矣"中的[之".接在主语[寡人"与介词结构[于国"之间.强调[于国"的意义.此句可译为[我对于治理 国家.可算是尽了心的了." 7. 衬音助词(不译).用在表示时间的词或某些动词的后面.凑足一个音节.它没有 实际意义.只是起着协调音节的作用.如<劝学>中的[不如须臾之所学也".[之"嵌在时间词[须臾"的后面.协调音节.作词缀.此句译作[比不上片刻学到的东西多".<谏 逐客书>中的[由此观之".这里的[之"接在动词[观"后面.协调音节.无义.此句可译作[从这看来" 8. 嵌在姓名中间.无实义.如[佚之狐言于郑伯曰".[若使烛之武见秦君".[介之推不 言禄".[宫之奇谏假道"中的[佚之狐".[烛之武".[介之推".[宫之奇". 9. 嵌在专用名词之间.无义.如<病梅馆记>中的[辟病梅之馆以贮之".前一个[之"用在[病梅馆"这个专用名词中.不译. 三. 作动词 用在处所句词前.可译作[到.往.去".如<鸿门宴>中的[项伯乃夜驰之沛公军".[之"用在处所名词[沛公军"前.作动词.之
